TECHNICAL FIELD

The invention mainly relates to the field of medical devices, inparticular to a body fluid analyte detection device.

BACKGROUND

The pancreas in a normal human body can automatically monitor the bloodglucose level and automatically secrete required amount ofinsulin/glucagon. In the body of a type 1 diabetes patient, the pancreasdoes not function properly and cannot produce enough insulin for thebody. Therefore, type 1 diabetes is a metabolic disease caused byabnormal pancreatic function, and diabetes is a lifelong disease. Atpresent, there is no cure for diabetes with medical technology. Theonset and development of diabetes and its complications can only becontrolled by stabilizing blood glucose.

Diabetics need to have their blood glucose measured before they injectinsulin into the body. At present, most of the testing methods cancontinuously measure blood glucose level and transmit the data to aremote device in real time for the user to view. This method is calledContinuous Glucose Monitoring (CGM).

When separating the transmitter from the bottom shell, the user needs toapply force in different directions. It requires multiple steps toseparate the transmitter from the bottom shell.

The user experience is poor.

Therefore, the prior art urgently needs a body fluid analyte detectiondevice that is simple and compact in structure, small in size andconvenient for users.

First Embodiment

FIG. 1 shows the sectional structure of the body fluid analyte detectiondevice and its installation unit in the embodiment of the invention.Before being installed on the human body, the bottom shell 10 of thebody fluid analyzer detection device is fixedly connected with theinstallation unit 1000.

FIG. 2 is the three-dimensional structure diagram of the body fluidanalyte detection device in the embodiment of the invention, and FIG. 3is the three-dimensional structure diagram of the installation unit inthe embodiment of the invention.

The detection device comprises the bottom shell 10, the sensor 113 andthe transmitter 12.

The bottom shell 10 is used for assembling the transmitter 12 and thesensor 113, and pasting the detection device on the skin surface. Thebottom shell 10 comprises a fixed part and a forced part. The bottomshell 10 is provided with at least one second clamp part 101. The secondclamp part 101 is used to engage the transmitter 12.

In the embodiment of the invention, the fixed part and the forced partare relative concepts. According to the structural design of the bottomshell 10 and the transmitter 12, the positions of the fixed part and theforced part can be selected differently.

In the embodiment of the invention, the connecting line l₁ of the twosecond clamp parts 101 divides the bottom shell 10 into A side and Bside. A side is equipped with a forced part, and B side is equipped witha fixed part.

Therefore, in the embodiment of the invention, the process of separatingthe bottom shell 10 from the transmitter 12 is as follows: fix the fixedpart on the B side with a finger, and apply a force F to the forced parton the A side with another finger in one direction to make the secondclamp part 101 failed, and then separate the second clamp part 101 fromthe first clamp part 121 to separate the transmitter 12 from the bottomshell 10.

In the embodiment of the invention, the forced part is a convex part 111facing outward from the side of the bottom shell. The shape, size andquantity of the convex part 111 are not limited. Preferably, the convexpart 111 is semicircular arc, which is convenient for users to presswith their fingers, saves space, and ensures a small and compact bottomshell structure.

In the embodiment of the invention, the number of the second clamp part101 is two. The two second clamp parts 101 correspond to the side wallsof the bottom shell 10.

In other embodiments of the invention, the number of the second clampparts 101 is four, and four second clamp parts 101 are correspondinglyarranged on the opposite side walls of the bottom shell 10, two on eachside.

In other embodiments of the invention, the number of the second clampparts 101 is six, and the six second clamp parts 101 correspond to theside walls of the bottom shell 10, with two on each side.

Here, the fixed part and the forced part are relative concepts.According to the structural design of the bottom shell 10 and thetransmitter 12, the positions of the fixed part and the forced part canbe selected differently, which will be described in detail below.

The installation unit 1000 is provided with a third clamp part 1001corresponding to the second clamp part 101, and the second clamp part101 is connected with the third clamp part 1001 by clamping to fix thebottom shell 10 on the installation unit 1000. When the user fixes thebottom shell 10 on the human body, the installation unit 1000 is alsofixed on the human body, which is convenient for the user to operatewith one hand.

While the bottom shell 10 is separated from the installation unit 1000,the installation unit 1000 installs the sensor unit 11 on the bottomshell 10, which briefly describes the steps for the user to install thesensor unit 11 on the bottom shell 10. The sensor unit 11 is used todetect the body fluid analyte parameter information.

The transmitter 12 is used for receiving the detection signal generatedby the sensor unit 11 and transmitting the signal wirelessly to theremote device. Therefore, transmitter 12 is electrically connected tosensor unit 11.

The transmitter 12 is provided with at least one first clamp part 121.The first clamp part 121 corresponds to the second clamp part 101. Thetransmitter 12 is assembled on the bottom shell 10 by clamping thesecond clamp part 101 and the first clamp part 121 to each other.Obviously, in the embodiment of the invention, the transmitter 12 isprovided with two first clamp parts 121, that is, two pairs of firstclamp parts 121 and second clamp parts 101 that clamp together with eachother.

Here, the first clamp part 121 corresponds to the second clamp part 101,which means that they are equal in number and corresponding in position.

When separating the bottom shell 10 from the transmitter 12, the fixedpart is fixed by a finger or other devices. When another finger or otherauxiliary devices are used to apply force to the forced part in onedirection, the bottom shell 10 will become failed. The second clamp part101 and the first clamp part 121 are separated from each other, thusseparating the transmitter 12 from the bottom shell 10. That is, whenseparating the bottom shell 10 and the transmitter 12, the user canseparate them by applying force to the forced part with only one fingerin one direction, which is convenient for the user to operate.

It should be noted here that failure is a conventional concept in thefield of engineering materials. After the failure, the material willlose its original function, and the failed part cannot be restoredagain. Since the second clamp part 101 is a part of the bottom shell 10,the failure of the bottom shell 10 comprises the failure of the bottomplate, side wall or the second clamp part 101 of the bottom shell 10.Therefore, the failure mode of the bottom shell 10 comprises one or moreof the bottom plate or side wall fracture of the bottom shell 10 (asshown in FIG. 5 b ), the bottom shell 10 fracture, the second clamp part101 fracture (as shown in FIG. 5 d ), and the plastic deformation of thebottom shell 10. Obviously, after the bottom shell 10 fails, the bottomshell 10 will lose the function and function of engaging the transmitter12.

The methods for fixing the fixed part comprise clamping, supporting,etc. There are no specific restrictions here, as long as the conditionsfor fixing the fixed part can be met.

Specifically, in the embodiment of the invention, the connecting line l₁of the two second clamp parts 101 divides the bottom shell 10 into Aside and B side. A side is provided with a forced part, and B side isprovided with a fixed part. Since the outer contour of the transmitter12 basically coincides with that of the bottom shell 10, the side of thebottom shell 10 in the embodiment of the invention is provided with anoutward convex part 111, which is convenient for applying force. Theconvex part 111 is the forced part.

The convex part 111 is arranged on the short side of the bottom shell10, and the two second clamp parts 101 are correspondingly arranged onthe long side of the bottom shell 10. The two second clamp parts 101 andthe two first clamp parts 121 are hooks. When separating the transmitter12 from the bottom shell 10, the convex part 111 in the embodiment ofthe invention is arranged on the same side near the two second clampparts 101, as shown in FIG. 1 . The convex part 111 is relatively closeto the two second clamp parts 101. Applying a small force on the convexpart 111 can make the second clamp part 101 failed, which is convenientfor users to separate.

Therefore, in the embodiment of the invention, the process of separatingthe bottom shell 10 from the transmitter 12 is as follows: fix the fixedpart on the side B with a finger, and apply a force F to the convex part111 in one direction with another finger to make the second clamp part101 failed, and then separate the second clamp part 101 from the firstclamp part 121, so as to separate the transmitter 12 from the bottomshell 10.

It should be noted that the embodiment of the invention does not limitthe positions of the convex part 111 and the second clamp part 101. Forexample, the convex part 111 can be arranged on the long side of thebottom shell 10, and the two second clamp parts 101 are correspondinglyarranged on the short side. Or the convex part 111 is far away from thesecond clamp part 101, so applying a greater force on the convex part111 can also make the second clamp part 101 ineffective and separatefrom the first clamp part 121. Or the second clamp part 101 can also bearranged on the bottom plate of the bottom shell 10, and there is nospecific restriction here.

In the embodiment of the invention, the shape of the top view of thedetection device is a rounded rectangle. The embodiment of the inventiondoes not specifically limit the shape of the top view of the detectiondevice, and its shape can also be rectangular, circular, elliptical orother shapes.

FIG. 4 shows the assembly structure of transmitter 12 and bottom shell10 in the embodiment of the invention.

The detection device also comprises a battery (not shown). The batteryis used to power the transmitter. The position where the battery is setis the battery position 123. Specifically, in the embodiment of theinvention, the battery is set in the transmitter 12. The battery is setin the transmitter 12, which can be charged for many times and reused toreduce the cost of users.

Since the battery has a certain volume, the bottom shell 10 of theembodiment of the invention is also provided with an assembly hole 103for assembling the battery part 123. Specifically, in the embodiment ofthe invention, after the battery part 123 is installed to the assemblyhole 103, part of the battery part 123 is exposed outside the bottomshell 10. And the convex part 111 is arranged on one side of theassembly hole 103. Therefore, when a force F is applied to the convexpart 111 to separate the bottom shell 10 from the transmitter 12, theexposed battery part 123 can be used as a support part for applying theforce F (for example, the thumb is supported on the exposed battery part123). At this time, it is equivalent to that the user's thumb exerts aforce opposite to the force F on the transmitter 12 to promote theseparation of the bottom shell 10 from the transmitter 12.

It should be noted that in other embodiments of the invention, theassembly hole 103 may not be set, that is, the battery part 123 iscompletely wrapped by the bottom shell 10 and is not exposed.

In the embodiment of the invention, a crease groove 102 is also arrangedat the position corresponding to the connecting line 11 on the bottomshell 10. The crease groove 102 can reduce the thickness of the bottomshell. The bottom shell 10 is more likely to fail along the creasegroove 102, and the separation operation is easier. Due to the assemblyhole 103, the crease groove 102 is located on the side wall of thebottom shell 10. It is obvious that the crease groove 102 can penetratethe bottom plate of the bottom shell 10 along the connecting line l₁without the assembly hole 103.

Preferably, in the embodiment of the invention, the bottom plate of thebottom shell 10 is also provided with a mounting hole 106 and a sensorunit 11 arranged in the mounting hole 106. The edge contour of thesensor unit 11 matches the edge contour of the mounting hole 106. Here,the matching of the two edge contours means that the two edges can fitinto each other.

One part of the sensor 113 is arranged on the sensor unit 11, and theother part enters the subcutaneous area. When installing the sensor 113,the sensor 113 is loaded by the sensor unit 11 and installed on thechassis 10. Preferably, in the embodiment of the invention, before andafter installation, the shape of the sensor 113 on the sensor unit 11does not change, that is, the sensor 113 and the sensor unit 11 aresimultaneously installed on the bottom shell 10. Therefore, afterinstalling the sensor 113, the sensor unit 11 becomes part of the bottomshell 10.

FIG. 5 a and FIG. 5 b are the structural diagrams of the side wall orbottom plate of the bottom shell 10 before and after failure. FIG. 5 cand FIG. 5 d are the structural diagrams of the second clamp part 101 ofthe bottom shell 10 before and after failure.

As previously mentioned, the first clamp part 121 and the second clamppart 101 are hooks. When a force F is applied to the forced part in onedirection, the bottom shell 10 is broken along the crease groove 102, asshown by the virtual coil C. In FIG. 5 c -FIG. 5 d , when the forcedpart is applied with force F in one direction, the second clamp part 101is broken.

In other embodiments of the invention, the first clamp part 121 and thesecond clamp part 101 can be respectively a card hole and a card block,or a card block and a card slot, and no specific restriction is madehere.

Second Embodiment

The difference between the second embodiment and the first embodiment isthat the battery is arranged on the bottom shell and there is noassembly hole. Other structures and connection modes are similar tothose in the first embodiment.

FIG. 6 is the three-dimensional structure diagram of the detectiondevice in the embodiment of the invention.

In the embodiment of the invention, the battery is arranged in thebottom shell 20. Therefore, the battery part 203 is located on thebottom shell 20. The top of the battery part 203 is flush with the topof the transmitter 22, which can reduce the thickness size of thedetection device. At this time, the bottom shell 20 is not provided witha convex part, but the battery part 203 is directly used as the forcedpart. As the battery part 203 is thicker and has a relatively largearea, as a forced part, it is easier for users to apply the force on thebattery part, optimizing the user's operation steps.

Similarly, two second clamp parts 201 are arranged on both sides of thebottom shell 20. Therefore, the third clamp part 1001 corresponding tothe installation unit 1000 is similar to the first embodiment. It can beunderstood by those skilled in the art that when the number, position,size and other parameters of the second clamp part in the secondembodiment change with respect to the second clamp part 101 in the firstembodiment, the third clamp part 1001 in the second embodiment will alsochange accordingly, so as to be able to engage with the second clamppart.

The connecting line l₁ of the two second clamp parts 201 divides thebottom shell into A side and B side. The A side is provided with thebattery part 203, which is used as the forced part, and the B side isused as the fixed part. When separating the bottom shell 20 from thetransmitter 22, fix the fixed part and apply force F to the battery part203 in one direction to make the bottom shell 20 failed, thus separatingthe transmitter 22 from the bottom shell 20.

FIG. 7 a shows the assembly structure of the transmitter 22 and thebottom shell 20 in the embodiment of the invention. FIG. 7 b is a topview of the bottom shell 20 in the embodiment of the invention.

As shown in FIGS. 7 a and 7 b , the crease groove 202 corresponding tothe connecting line l₁ penetrates the bottom plate of the bottom shell20. When the first clamp part 221 is separated from the first clamp part201, the bottom shell 20 is broken along the crease groove 202.

Since the battery needs to supply power to the transmitter 22, thebottom shell 20 is also provided with at least one connection hole 204.The transmitter 22 is electrically connected with the anode and cathodeelectrodes of the battery through the connection hole 204.

The connection hole 204 can be provided with an electrical contact whichcan be electrically connected with the transmitter 22. Or thetransmitter 22 is provided with a protruding electrical connection endthat can be inserted into the connection hole 204. Or the battery can beelectrically connected with the transmitter 22 through the wire passingthrough the connection hole 204 or the lead plated on the surface of thebottom shell 20.

It should be noted that in other embodiments of the invention, theconnection hole 204 may not be set, and the transmitter 22 and the twopoles of the battery are electrically connected through the lead wirecompletely coated on the surface of the bottom shell 20, which is notspecifically limited here.

Preferably, in the embodiment of the invention, in order to seal theelectrical connection position, a sealing ring 205 is arranged aroundthe connection hole 204.

In general, the elastic sealing material plays a sealing role afterbeing squeezed. In the embodiment of the invention, the extruded sealring 205 exerts certain elastic force on the transmitter 22. Whenapplying force F to the forced part, the sealing ring 205 provides theelastic force to promote the separation of the transmitter 22 from thebottom shell 20.

Preferably, in the embodiment of the invention, in order to seal theconnection position between the transmitter 22 and the sensor, a seal(not shown) is arranged around the sensor. Similar to the above sealring 205, when applying force F to the forced part, the seal alsoprovides the elastic force to promote the separation of the transmitter22 from the bottom shell 20.

It should be noted that since the electrical connection position betweenthe transmitter 22 and the battery or the connection position betweenthe transmitter 22 and the sensor is relatively good, other embodimentsof the invention may not be provided with a seal ring 205 or a seal.

For the failure mode of the bottom shell 20, the function of themounting hole 206, the type and engagement mode of the first clamp part221 and the second clamp part 201, please refer to the previousdescription, and will not be repeated here.

In other embodiments of the invention, the transmitter 22 part mountedon the bottom shell 20 can also be a forced part, which is notspecifically limited here. It should be pointed out here that althoughthe force F may directly act on the transmitter 22, the actual effect ofthe force F is only displayed on the bottom shell 20, that is, the forceF only changes the shape of the bottom shell 20 (such as shape andstructure changes), but does not change the shape of the transmitter 22.At this time, it can still be considered that the user is the forceexerted on the forced part of the bottom shell 20.

Third Embodiment

Compared with the previous embodiment, the third embodiment is differentin that only one first clamp part is set on the transmitter, only onesecond clamp part is correspondingly set on the bottom shell, and theshape of the top view of the detection device is oval.

FIG. 8 is the structural diagram of the detection device according tothe embodiment of the invention, which only comprises a first clamp partand a second clamp part.

A first clamp part and a second clamp part are engaged with each otherat D, that is, there is only one pair of first clamp parts and secondclamp parts engaged with each other. The bottom shell 30 comprises aconvex part 311. The convex part 311 is a forced part, and the rest ofthe bottom shell 30 is a fixed part. By applying force to the convexpart 311, the bottom shell 30 fails, and the first clamp part and thesecond clamp part are separated from each other, thus separating thetransmitter 32 from the bottom shell 30.

For the failure mode of the bottom shell 30, the types and engagementmodes of the first clamp part and the second clamp part, please refer tothe above, and will not be repeated here.

It can be understood by those skilled in the art that the installationunit 1000 is also provided with a third clamp part corresponding to thesecond clamp part. When the number, position, size and other parametersof the second clamp part in the third embodiment change with respect tothe second clamp part in the first embodiment, the third clamp part inthe third embodiment will also change accordingly to engage with thesecond clamp part.

Fourth Embodiment

Compared with the previous embodiment, the fourth embodiment isdifferent in that the detection device comprises a plurality of forcedparts.

It can be understood by those skilled in the art that the change in theimplementation mode of the forced part structure does not cause theclamping structure and the clamping relationship of the first clamppart, the second clamp part and the third clamp part, so it will not berepeated here.

FIG. 9 is a top view of the detection device of the embodiment of theinvention, which comprises two forced parts.

In the embodiment of the invention, the transmitter 42 is provided withfour first clamp parts, and the bottom shell 40 is also correspondinglyprovided with four clamp parts. The two corresponding first clamp partsand the second clamp parts engage with each other at D1-D1′ and D2-D2′respectively, that is, four pairs of first clamp parts and second clampparts engage with each other. On the bottom shell 40, the connectinglines of D1-D1′ and D2-D2′ are l₂ and l₃ respectively. The A side and Bside of l₂ and l₃ are respectively provided with a force applying partand a fixed part. l₂ and l₃ divide the bottom shell 40 into a forcedpart, a fixed part and a forced part. In the embodiment of theinvention, two forced parts are arranged on both sides of the bottomshell 40, and a fixed part is arranged between the two forced parts.

When separating the transmitter 42 and the bottom shell 40, two thumbsare supported below the fixed part to fix the fixed part, and two indexfingers apply force to the forced part in one direction on both sides ofthe detection device, making the bottom shell 40 more likely to fail.

For the failure mode of the bottom shell 40, the types and engagementmodes of the first clamp part and the second clamp part, please refer tothe above, and will not be repeated here.

It should be noted that other embodiments of the invention can also beprovided with more first and second clamp parts. When separating thetransmitter from the bottom shell, at least one pair of first and secondclamp parts fail (similar to the way shown in FIG. 8 ), or two pairs ofcorresponding first and second clamp parts fail (similar to the wayshown in FIG. 4 and FIG. 7 a ), or multiple pairs of corresponding firstand second clamp parts fail (similar to the way shown in FIG. 9 ).

To sum up, the invention discloses a body fluid analyte detectiondevice. On the one hand, before the bottom shell is installed on thehuman body, the bottom shell is fixed with the installation unit, andthe sensor is located in the installation unit and separated from thebottom shell. When the bottom shell is separated from the installationunit, the installation unit simultaneously installs the sensor on thebottom shell, reducing the steps of installing the sensor on the bottomshell. On the other hand, the installation unit only applies force tothe forced part of the bottom shell in one direction, the utility modelcan make the bottom shell failed, thereby separating the first clamppart from the second clamp part, reducing the user's operation stepswhen separating the transmitter from the bottom shell, and enhancing theuser's experience.
